I seem to have met with some difficulty in removing my tub to repair the walls and retile. my problem lies indisconnecting the tub from the drain. the tub is 12-15 years old. I imagine it's a steel tub with a ceramic coating. and the drain is a non pop up type. the tub is fairly light. the drain connects to the tub via abs plastic pipes. the problem is that I cannot get underneath the tub to undo the pipes. is there a way to disconnect the drain pipe at the top from the outside surface of the tub without having to get underneath to unhook the pipes? does the drain in the tub pop out or unscrew to make removing it easier?
